IMPROVEMENT IN CANDLE-LAMPS.

Specification forming part of Letters Patent No. [86,139, dated January9, 1877; application filed October 18, 1876.

.To all whom it may concern:

Be it known that I, CHARLES KIENLE, of New York city, in the State ofNew York, have invented certain new and useful Improvements relating toLamps, of which the following is a specification:

The illuminating agent in my device is a candle of cylindrical exterior,made of proper materials, and with a properly-proportioned wick, toallow of being held in a suitable candle-holding lamp, and being forcedup by a spring from below as the upper portion is consumed away by use.Lamps adapted to thus inclose and force up candles have been long knownand are highly appreciated.

My invention is intended more particularly for that class of lamps,though some portions may be applied on lamps of a different character.

I have devised an improved form of spring, which cleans itself when ithas, by any chance, accumulated melted fat, and gives reliable actionwithin a long range of motion, and with less depth of easing than isrequired with the ordinary spring.

I have devised a form of the candle-holding parts which involves littlechance of melting down the fat, and have provided means for dischargingit through the sides in case melted fat does flow down. I have alsoprovided an improved means for engaging and disengaging the parts inopening and closing the lamp, and in applying or removing the globe orshade.

The following is a description of what I consider the best means ofcarrying out the invention.

The accompanying drawings form a part of this specification.

Figure 1 is a vertical section through the entire lamp, with aportion ofthe globe broken away. Fig. 2 is a horizontal section through the upperportion on the line S S. Fig. 3 is a corresponding section through thelower portion on the line T T.

Similar letters of reference indicate corresponding parts in all thefigures.

A is the main casing, inclosing the candle and a spring. A is aremovable foot-piece, connected by a bayonet-joint, and B is a longvolute spring of sheet-steel, coiled upon itself in the positionrepresented, with just sufficient tightness to enable it to clean itselfcompletely from all fat when the springs is presed home upon itself. Itssmaller end encircles a pin, 0, extending downward from the center ofthe candleseat G, which supports the candle M, forcing it constantlyupward into the contracted portion represented in the removable cap ACandles accurately formed without taper are ordinary articles ofmerchandise. The candle M is of that character. The upper end of themain casing A is contracted to fit closely to the candle, while the mainbody of the casing A and the candle-seat O are of considerably largerdiameter. The cap A has an aperture in its contracted top smaller thanthe diameter of the candle. The cap is enlarged below, so as to leave aconsiderable annular space between its inner surface and the exterior ofthe main casing A. This cap is litted with a bayonet -joint for readyremoval, and has liberal perforations a. A is an internal rim, whichprojects inward near the bottom of the cap A and fits tightly againstthe exterior of the casing A.

The candle is held with a clear air -space around it, except at theextreme upper end. If the candle commences to drip or run, the meltedfat is likely to flow down the space between the casing A and the cap A,and out through the apertures a but in case any fat should, by anychance, tend to clog the spring B, the spring is self-clearing. Thesimple act of compressing it causes each fold or convolution to rubagainst its mate, and detach any fat which may have adhered. It isdesirable to retain as highly-glazed surface as practicable on thespring to compel the hardened fat to thus peel off more cleanly.

To the exterior of the casing A is soldered or otherwise firmly attacheda large drip-cup, D, formed with an internal flange, D under which arebeveled cams D the functions of which will presently appear. A stoutring or casing, G, is firmly supported by means of a bracket, F, adaptedto be screwed or otherwise secured to the wall of a car, or otherstructure in which the lamp is to be used, Except for the catches orbeveled spurs H. the flange and cams D D of the drip-cup D may slidefreely upon the exterior of the case G. Beveled spurs H protrude throughapertures in the casing G,"and are forced outward by springs h, rivetedor otherwise attached to the interior of the casing G, as plainly shownin Fig. 3. To connect the candle-holder and its attachments, it issimply necessary to thrust it directly upward from below. The beveledsurfaces of the spurs H, on being struck by the internal rim D moveinward by the yielding of the springs h, and allow the rim to rise past,when the spurs H snap out and engage and hold it for an unlimitedperiod.

To disengage these parts the casing A and its attachments are turnedpartially around in their seat. This motion brings the beveled pieces D,which I have denominated'cams, into contact with the spurs H, andpresses them inward. This done, the candle-holder and its connectionsmay be drawn down and removed.

The same means are employed for connecting and disconnecting the glassglobe I, its

base being provided with a metal ring with the proper internal lip orflange, adapted to act against correspondingly-beveled spurs, the bevelof these spurs being on the upper instead of on the lower faces.

A modification of the same device is employed for engaging and releasingthe shade J. The shade is formed above the flaring body, with agenerally-cylindrical neck, J, having two beads,j. The fixed casing O,supported by a bracket to the wall, carries a ring, L, capable of beingturned partly around upon the casing O. The ring carries beveled cams Lmounted in an annular internal recess, and which act against projectionsP, which are supported by springs 10, and play through openings in thefixed casing O. The springs 12 press outward. When the ring L is in theposition shown in Figs. 1 and 2, the projections P are pressedinward,and engage between the beadsj of-theshade and support it. When itis desired to remove it, the ring L is turned into 'such diflerentposition that the cams L are moved out of contact with the stops P, andthe latter being pressed out with provisions, a, for discharging thegrease,

as herein specified. v

3. In a'lamp having detachable parts, as specified, the engagingwspurs Hand springs h on the one part, in combination with the flange or rim Dand Scams D on the other part, adapted to engage? by .a direct thrust,and toseparate by a turning motion, as herein specified.

4. The turning ring L, having internal cams L and turning upon the fixedpart 0 of the lamp, in combination with the beveled catches or spurs P,acting springs 1), with the beaded neck J j of the lampshade, as hereinspecified.

In testimony whereof I have hereunto set my hand this 17th day ofOctober, 1876, in the presence of two subscribing witnesses.
